Very beautiful lake. You do see a few people by the lake fishing and walking around. Took my dogs and they loved it. pretty short walk. Easy hike there.

Don’t miss the view up past the lake! So tranquil. Lovely fall colors with the aspen grove were why we came back today.

Road marked closed at entrance as of 10/9.

Easy to moderate hike, about 5.14 miles long. Started at Red Meadows Resort (stop 10), hiked to Rainbow falls, than to Devils postpile and returned to stop 10. The trails are maintained very very well.

beautiful aspens, distant waterfalls, this trail has it all. In spring, Wooley Mules Ears. Trail obviously used by pack team but its fairly easy although the elevation/rocky terrain makes it moderate. Its the journey, not the destination! Take some time to visit the mine relecks, so cool!

I absolutely love this hike!! Hiking to the lake is a bit of a work out going up and definitely got your heart pumping. Although, it was short and lots of shade. So it wasn’t too bad. Very beautiful lake!! There wasn’t many people. Took our time walking around the lake and taking in the scenery. It was easy going back down the trail. I would definitely come back again. It was worth the hike.

Gorgeous, well maintained trail with lots to see. Beautiful views and varied terrains make this one an excellent trail. Good for all levels of hikers.

if you're like me-- born and raised in the NJ watershed and New Orleans (6 feet BELOW sealevel)-- this is some serious elevation, as is all of Mammoth Mountain-- take. your. time. this is an easy trail, but it is not easy for those of us who are used to being at or below sea level. it will be frustrating to pace yourself, especially if you're athletic with hiking experience, but the top of the glacier-polished postpile is breathtaking-- I wish the photos I took could do it justice. for sea-levelers, I recommend walking to Rainbow Falls first, taking a 15 minute break, then moving toward the top of the postpile. The glacier-striated hexagonal columnar basalt up there looks like a damn-near perfect tile patio job. try to be on top of the postpile around golden hour-- real treat.

Ugh...HATED this hike.

We went on a weekday morning in early September and came across SIXTEEN PEOPLE in the first .2 miles, and turned around and left and hiked Fern Lake instead. This trail was BUSY. AllTrails rates it as the #1 hike in the Inyo Forest, and it seems the word is out. SO MANY PEOPLE on the trail. I guess some folks like hiking in huge crowds. We hike to ESCAPE the crowds, and this was the Times Square on NYE equivalent of Mammoth Mountain lake hikes, so be forewarned!

My husband and are in our 70’s and we hiked it with a little effort. Very beautiful lake! Would go again in a minute!

Trail was hard for us to follow, became lost a couple of times. We are beginners so might chalk it up to that. Overall great hike though the elevation got to us a bit.

Beautiful trail with lots of wildflowers in the summer and fall colors after September

Took the shuttle in (stop 6) and hiked down the trail to the falls. Shuttle is $8 per person round trip. The trail can be pretty heavily trafficked at times, especially in the summer , especially around the shuttle stops. Between stops, the traffic on the trail decreases significantly, which leads to a very pleasant walk.

Reaching the Postpile Monument is quite interesting with a trail going to the top and another at the bottom. The view at the top is nice but not worth it if you're pressed for time. The trail at the bottom offers more interesting photo opportunities.

Hiking to rainbow falls is fairly easy. The trail is well maintained overall and not heavily trafficked. The crowds do increase quite a bit when you reach close to the falls as the views impress. The viewpoints in a couple spots are quite good.

Hiking back up to the bus stop (stop 10) is a bit hard. It may be the elevation that adds to it but it's harder than any other part of the trail.

A bit steep at times, but nothing we sea level people could not handle. The lake is clear and worth the effort!

Lovely hike! We managed our way from LA to the trailhead in one day and got down before sunrise. We started at 4:30PM (maybe a little later) and we were back down by 6:30, at the brewery by 7. There is a lot of variety on the trail, starting with some meadow views, then some time through the woods and then on top of a ridge line which brings you to the lake. We were the only ones on the trail and at the lake which gave us a feeling of peacefulness and seclusion. The lake is clear and clean and if you go just a bit past the lake you'll find yourself on a ledge overlooking the stunning mountains surrounding the area. Some other reviewers mention a huge incline, but I would call it a pretty average incline for an uphill hike. Certainly was not unmanageable, and we enjoyed getting our blood pumpin'.

Stopped here with a group of Boy Scouts on the last day of a 3 nighter into Purple and Pika Lakes. Found a great campsite on the peninsula at the northwest end of the lake and had the place to ourselves for the night even at the height of summer.. Spoke with a fellow fisherman early in the afternoon and we both were getting skunked until he headed back to Mammoth Lakes and I quickly hooked 4 Golden Trout (I released them all). It wasn't until I got back to my computer that I learned there aren't recorded to be Golden in that lake. Beautiful spot, surprisingly pristine and natural despite the proximity to the trailhead. Thanks to all for keeping it that way!!

Easy hike with kids even for a fat guy like myself. We enjoyed exploring around the lake, meeting a bunch of friendly dogs, and quick hellos to other families.

Had to take the shuttle in, I think 8 dollars round trip, but I think you can drive in before 830am but the road is narrow and buses are hard to get around. 10 dollars per car at the entrance pass the adventure center. Dogs need to be muzzled. Try not too take your dog if she/he is aggressive. Bus drivers don't like to take too many dog per trip so you may be asked to take the next bus. The drive is 30 miles. I have a lab so she barely fit underneath or in front of me. If you have a dog, make sure to get a seat. They have standing room but it's hard with a big dog.

Stop 6: Devil Postpile-0.5 miles; Rainbow Falls- extra 1.5-2miles (trail to lower falls is closed 2018) two viewpoints top of falls and lower falls viewpoints. First viewpoint to lower viewpoint is steep so climbing up is a pain. Trail itself is ok. Kinda up and down in elevation but not too steep. Well marked trail. Can deviate to the river to play in the water with dogs. You can also hike to the Mina--- Falls.

Stop 10: The other way to get in or get out: around 1 mile from rainbow falls. This trail is mildly challenging from falls to the stop so it's easier to walk down from this stop but you just see the falls. You are mostly gaining elevation coming back up. Pretty with wildflowers and Forest trees. Passes the PCT trail. There is a resupply general store here and a little restaurant that is heavily overpriced ($10+ hamburgers and $10 milkshakes)

The adventure center has tickets for the gondola and kid challenge structure/ rock wall. You can get a combo of gondola and shuttle 37 dollars each. Morning is best for gondola. No lines. But the food up there does not open till lunch. Summer time is for mountain/dirt bike and a beautiful view at the top. Construction at the top. The museum is nice for kids.

Cons: due to recent fires air quality and visibility was sub par.

Very nice stream running next to the trail. I was rather disappointed with the condition of the lake. It has been stagnant for quite some time and it not ideal for swimming.

Very busy trail at the end of July. Yosemite Valley was closed due to fires. Which explained the heavier crowds in Mammoth Lakes. As on all trails, take plenty of water for everyone in your group. Try the west side of the river. Much fewer people.

Cool little loop to see this amazing monument. We got off at Shuttle stop #6 and you can continue onto Rainbow Falls at the tail end of the loop. Steep incline to the top but if that's a problem you can just view it from below which is the main focus anyway. Air quality was fine despite the fires but it was dry, hot and windy so bring enough water.

We started at the Rainbow Falls trailhead off of the Red Meadows Shuttle stop #9 which is a shorter hike than this one (1.3 miles one way so 2.6 round trip) You can change it up on the way back and take the Reds Meadow Resort path back to Shuttle stop #10 which is recommended to get out because it is the last shuttle stop and usually fills up the shuttles leaving the area. The trail to the base of the Falls is closed now for 2018 for rerouting and restructuring and will reopen in 2019. Air quality was fine despite the fires but it was dry, hot and windy so bring enough water. The waterfall was beautiful and well worth the hike according to my seven year old!
